Here is the example above done correctly to the new API

In your main, when you want to start a notification instantiate the class:

NotificationPanel nPanel = new NotificationPanel(MyActivity);

And when you want to cancel notification: (as it is an onGoing notification)

nPanel.notificationCancel();    

Then create the class for the notification caller:

public class NotificationPanel {

private Context parent;
private NotificationManager nManager;
private NotificationCompat.Builder nBuilder;
private RemoteViews remoteView;

public NotificationPanel(Context parent) {
    // TODO Auto-generated constructor stub
    this.parent = parent;
    nBuilder = new NotificationCompat.Builder(parent)
    .setContentTitle("Parking Meter")
    .setSmallIcon(R.drawable.ic_launcher)
    .setOngoing(true);

    remoteView = new RemoteViews(parent.getPackageName(), R.layout.notificationview);

    //set the button listeners
    setListeners(remoteView);
    nBuilder.setContent(remoteView);

    nManager = (NotificationManager) parent.getSystemService(Context.NOTIFICATION_SERVICE);
    nManager.notify(2, nBuilder.build());
}

public void setListeners(RemoteViews view){
    //listener 1
    Intent volume = new Intent(parent,NotificationReturnSlot.class);
    volume.putExtra("DO", "volume");
    PendingIntent btn1 = PendingIntent.getActivity(parent, 0, volume, 0);
    view.setOnClickPendingIntent(R.id.btn1, btn1);

    //listener 2
    Intent stop = new Intent(parent, NotificationReturnSlot.class);
    stop.putExtra("DO", "stop");
    PendingIntent btn2 = PendingIntent.getActivity(parent, 1, stop, 0);
    view.setOnClickPendingIntent(R.id.btn2, btn2);
}

public void notificationCancel() {
    nManager.cancel(2);
}
}    

Then add the return class that accept the pending intent:

public class NotificationReturnSlot extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    String action = (String) getIntent().getExtras().get("DO");
    if (action.equals("volume")) {
        Log.i("NotificationReturnSlot", "volume");
        //Your code
     } else if (action.equals("stopNotification")) {
         //Your code
        Log.i("NotificationReturnSlot", "stopNotification");
     }
     finish();
    }
}

Then you need to make a XML file for the button. This is a simple one:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >

<Button
    android:id="@+id/btn1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:text="volume" />

<Button
    android:id="@+id/btn2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:text="Stop" />

<TextView
    android:id="@+id/message"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@+id/msglbl" />

Last and not least, the Manifest file:

   <activity android:name=".NotificationReturnSlot"
        android:launchMode="singleTask"
        android:taskAffinity=""
        android:excludeFromRecents="true"/>
